Motorized scooter

Abstract

A scooter having a fuselage with a front portion and a rear portion that includes a rear wheel rotatably mounted at the rear portion. The scooter also includes a standing platform supported by the fuselage for supporting a rider and a transmission system mounted under the standing platform in the rear portion of the fuselage. The transmission system having a motor with a wheel engagement element being operatively coupled with the rear wheel to allow the wheel engagement element to rotate the rear wheel when the wheel engagement element is engaged with the rear wheel. Another embodiment of the transmission system includes a motor, a first drive cone coupled the motor; and, a drive cone engagement mechanism configured to allow the first drive cone to be operatively coupled with a wheel to rotate the wheel.

       16 . The scooter of  claim 9 , where the fuselage is tubular in shape.  
   
   
       17 . The scooter of  claim 9 , where the rear wheel includes a sidewall and the wheel engagement element is shaped to engage the sidewall.  
   
   
       18 . The scooter of  claim 9 , where the transmission mechanism further comprises a second motor with a second wheel engagement element mounted in parallel to the motor and operatively coupled with the rear wheel to allow the second wheel engagement element to rotate the rear wheel when the second wheel engagement element is engaged with the rear wheel.  
   
   
       19 . The scooter of  claim 9 , where the transmission mechanism includes a hinged mechanism to control the contact between the wheel engagement element and the wheel.  
   
   
       20 . The scooter of  claim 19 , where the hinged mechanism is operable by a cable to control the contact between the wheel engagement element and the wheel.  
   
   
       21 . The scooter of  claim 19 , where the hinged mechanism is normally in a state that allows the wheel engagement element to be engaged with the rear wheel.  
   
   
       22 . The scooter of  claim 19 , where the hinged mechanism is normally in a state that allows the wheel engagement element to be disengaged with the rear wheel.  
   
   
       23 . The scooter of  claim 9 , where the motor includes a shaft having a first end and a second end, wherein the wheel engagement is mounted on the first end and a tachometer system is mounted on the second end.  
   
   
       24 . The scooter of  claim 23 , wherein the tachometer system comprises a tachometer disk mounted on the second end of the shaft of the motor.  
   
   
       25 . The scooter of  claim 24 , wherein the tachometer disk includes a plurality of openings displaced around the second end of the shaft of the motor.  
   
   
       26 . The scooter of  claim 23 , wherein the tachometer system comprises an optical encoder mounted on the second end of the shaft of the motor to determine a rotation of the shaft of the motor.
